Subject: Issuance of NPDES Permit NC0085928
American Truetzschler
Mecklenburg County
Dear Mr.Jaekel:
Division of Water Quality(Division)personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly,we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of
North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.Environmental
Protection Agency dated May 9, 1994(or as subsequently amended). The following changes have been made to the draft version of
your permit:
• The monitoring frequency for 1,1-dichloroethane was incorrectly listed as twice per month. As with the other
pollutants of concern at this facility,1,1-dichloroethane should be monitored monthly. The appropriate changes
have been made to part A. (1.).
• The pH monitoring requirement and limit has been eliminated. This was not a requirement in your previous
permit nor is it a requitement in the general permit for groundwater remediation (NCG510000). It was a typographical
error and has been removed.
• The cover page of your draft permit incorrectly listed the receiving stream for your discharge as"an unnamed tributary
to Polecat Creek in the Cape Fear River Basin." This has been corrected to read"an unnamed tributary to the Catawba
River in the Catawba River Basin."
Please be aware that this permit does not become effective until October 1,2001. You are bound to the limits and
monitoring requirements of your current permit through September 30,2001.
If any parts,measurement frequencies or sampling requirements contained in this permit are unacceptable to you,you have
the right to an adjudicatory hearing upon written request within thirty(30) days following receipt of this letter. This request must be in
the form of a written petition,conforming to Chapter 150B of the North Carolina General Statutes,and filed with the Office of
Administrative Hearings (6714 Mail Service Center,Raleigh,North Carolina 27699-6714). Unless such demand is made,this decision
shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require modification or
revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may be
required by the Division of Water Quality or permits required by the Division of Land Resources,the Coastal Area Management Act
or any other Federal or Local governmental permit that may be required.
If you have any questions concerning this permit,please contact Natalie Sierra at telephone number(919) 733-5083,
extension 551.
Sincerely,

A. (2.) CHRONIC TOXICITY PERMIT LIMIT(QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the"North Carolina
Ceriodaphnia Chronic Effluent Bioassay Proceured ," Revised February 1998,or subsequent versions or"North Carolina
Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998)or subsequent versions.The tests will
be performed during the months of February,May,August and November. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit,then
multiple-concentration testing shall be performed at a minimum,in each of the two following months as described in"North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998)or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival.The defmition of"detectable impairment," collection methods,exposure regimes,
and further statistical methods are specified in the"North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised-February 1998)or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring
Form(MR-1)for the months in which tests were performed,using the parameter code TGP3B for the pass/fail results and
THP3B for the Chronic Value.Additionally,DWQ Form AT-3 (original)is to be sent to the following address:

To: "Natalie Sierra" <[e-mail]>
Ms. Sierra
I reviewed the Draft NPDES Permit dated June 20, 2001. Based on my �J ,�t5
review every thing looks OK except for monitoring requirements. First the
monitoring table shows that 1,1-dichloroethane is required to be tested
twice per month where everything else under the same sampling method is only
required monthly. I would prefer this to be only monthly as I assume this
was probably a typing error. If it was not could you give me justification VAS
for requiring twice a month for this constituent. Secondly the Standard pHe
is listed as not allowing the pH to fall below 6.0 standard limits. First Oat-ln
of all I would prefer this to only be conducted quarterly along with the 7mv.r(plw
Chronic toxicity testing. If this is not exceptable could you give me some
explanation as to why it must be done monthly. Secondly the pH observed inS
the natural ground water within the Piedmont region is typically slightly on
the acidic side and it is not unusual for the pH to fall below 6.0 standard A
units. This could be a problem for us. The limestone bed should help kZ°.-JsrT adjust the pH limits prior to discharge, but I am concerned that this limit
will cause us more problems as the naturally occurring ground water pH is
typically in the 5.2 to 6.2 range. Since this is a naturally occurring event
in the ground water could this limit be adjusted to accommodate the ,
naturally acidic ground water. I would prefer the discharge pH limit to be
5.0 to 8.0 to accommodate the naturally occurring pH observed. The amount -i(, ,o
of water that would actually reach the Catawba Rive is minimal with the 01d'
distance that the discharge water would have to travel. Most of the water
will migrate into the soil before it ever reached the river. I appreciate
your help in this matter and want to give you the assurance that American
Tuetszchler, Inc. and CEI will make every effort to comply with the final
NPDES permit.
I will follow this email with an official request to amend the permit to
accommodate the changes identified above. I just wanted to get you my
comments in a timely manner to expedite the permit renewal. Again thank
your for your help in this matter.

BACKGROUND
The subject facility was initially permitted in 1996 for the treatment of groundwater
contaminated by chlorinated organic solvents. An Authorization to Construct for an equalization
tank, particulate filter, and air sparging system was granted on January 10, 1997. Since March
2000, the system has experienced toxicity problems that have caused the owners to cease
discharge while a Toxicity Reduction Evaluation (TRE) is performed. The results of this study
indicate that zinc is likely to be the cause of the toxicity. A January 5, 2001 ATC gave
authorization to construct a sodium cation exchange system and limestone filter bed to aid with
toxicity problems. It is the understanding of the Mooresville Regional Office that the system has
restarted and has resumed discharging.
Instream Monitoring and Verification of Existing Conditions and DMR Data Review.
Data dating from January 1998 through March 2001 were reviewed. As mentioned
above, the facility has not discharged since March 2000 and all DMRs from this point onward
verify non-discharge. Average flow for 1998-2000 is reported by the permittee as 11435 gallons
per day.
The facility monitors for flow, 1,1-dichloroethene, 1,2-dichloroethane,
tetrachloroethylene (PCE), trichloroethylene (TCE), 1,1-dichloroethane, 1,1,1-trichloroethane,
and chronic toxicity. Data from the 1998-1999 DMRs were used to assess reasonable potential
for 1,1-dichloroethene, 1,2-dichloroethane, PCE, TCE, 1,1-dichloroethane, and 1,1,1-
trichloethane below.
Results of Reasonable Potential Analysis (RPA):
Fact Sheet
NPt)FS NC0085928 Rcrio%al
I'agc I

A reasonable potential analysis (RPA) was performed for all monitored parameters. It
was determined that there is reasonable potential for violations of instream standards of 1,1-
dichloroethene and 1,2-dichloroethane,both of which are already limited in the current permit.
TCE is also limited in the current permit and monitored monthly. Due to recent changes in the
treatment system (January 2001 ATC), this limit will remain in the permit. The remaining
parameters will continue to be monitored on a monthly basis.
Correspondence:
The inspection reports describe the facility as well maintained with toxicity problems in
the effluent. The facility has received an NOV following a 2000 inspection, largely for
deficiencies in self-monitoring (violation of the daily maximum limit for 1,1-dichloroethene and
six failures of the chronic toxicity test). In January 1999 and March 2000, the facility received
NOVs and was eventually assessed civil penalties for toxicity violations. Correspondence
between the Aquatic Toxicity Unit (ATU) and the permittee indicates that the source of the
toxicity is in all likelihood, elevated zinc concentrations. ATU suggests that this may come from
piping within the system. The 2001 ATC allowed treatment improvements that were to remove
zinc and reduce toxicity.
Included with the renewal application was an Engineering Alternatives Analysis (EAA)
evaluating discharge alternatives. Given the urban location of the facility, surface water
discharge appears to be the most feasible option at this time.
PERMITTING STRATEGY AND SUMMARY OF PROPOSED CHANGES
No changes are proposed to this permit. The facility will be advised via cover letter that
should toxicity problems persist, a more comprehensive EAA should be performed to evaluate
non-discharge alternatives.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE
Draft Permit to Public Notice: June 20,2001
Permit Scheduled to Issue: August 13, 2001

Wilkesbor. 'aceway Park WWTP
NPDES C-rmit Application
Permit '4C0077607
Wilk. County
Dear Mr. Dunn:
The Division of Water Quality recei -d the Wilkesboro R. eway Park's request for an NPDES Permit on
April 6, 2001. I have completed an itial technical eview of the application package and require
additional information in order to fully .ssess the p •posed discharge. Please consider the comments
below and provide a revised Engineeri . Altern. Ives Analysis (EAA) accompanied by a written
response by June 11,2001.
The overall concern with this application is t : the discharge is sporadic, which may make treatment
plant operation difficult. You must demonstra 'at your current method of disposal is considerably less
feasible than discharge to surface waters. •eci 1,.11y, you must include among your cost analysis of
discharge alternatives the current, non-disc•.rge met od of disposal as well as the potential for an onsite
wastewater treatment system. These, and e cost of su i ace water discharge, must be given in terms of a
present value cost(see attached guidanc- document).
If we do not receive a response from •u,the NPDES appli•:tion submitted on April 6th will be returned
to you. Should the Division decide • issue a permit for your acility, you may anticipate that the permit
will be similar to that issued in :y 1999. If you have any q b-stions about the above comments, or if
you cannot provide the request,d information by the above d. e, please call me at [phone],
extension 551.
Sincerely,

2. Residuals handling and utilization/disposal scheme: Solids generation is not expected.
3. Treatment plant classification: Class I (no change from previous rating)
4. SIC Code(s): 3552 Wastewater Code(s): 66 Main Treatment Unit Code: 55008
PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant Funds or are any public monies
involved (municipals only)? No. Public monies were not used in the construction of this
system.
2. Special monitoring or limitations(including toxicity)requests: None at this time
3. Important SOC,JOC or Compliance Schedule dates: (please indicate) N/A.
4. Alternative Analysis Evaluation:
a. Spray Irrigation: Insufficient suitable land area available for a spray irrigation
system.
b. Connection to Regional Sewer System: No regional sewer system currently available
to the site. Even if regional sewer was available to this site, it is doubtful that the
regional authority would accept the treated GW into the collection system due to
hydraulic constraints.
c. Subsurface: Insufficient suitable land area available for a subsurface disposal
system.
5. Air Quality and/or Groundwater concerns or hazardous materials utilized at this facility that
may impact water quality,air quality or groundwater? The treatment facility is to remediate
groundwater that has been contaminated with chlorinated organic solvents. Contaminated
groundwater is recovered and treated prior to discharging to a storm-water detention basin
and eventually entering an unnamed tributary to the Catawba River. No hazardous materials
are stored and/or used at this facility. Impacts, if any,on the environment should be
minimal.

PART IV-EVALUATION AND RECOMMENDATIONS
American Truetzschler, Inc. requests renewal of their NPDES Permit for the discharge of
treated GW from a GW remediation facility located on Moores Chapel Road in western
Mecklenburg County. Changes the GW remediation facility since the permit was last issued are
detailed in Part II,No. 1(d) above. The groundwater has been contaminated with chlorinated
organic solvents. After treatment,the recovered groundwater is discharged into a stormwater
detention basin,which eventually enters an unnamed tributary to Catawba River.
Pending a final review and approval by the NPDES Unit, it is recommended that the NPDES
Permit be renewed as requested.

ALTERNATIVE DISCHARGE OPTIONS
Below are the alternative discharge options, which American
Truetzschler, Inc. (ATI) and Cooper Environmental Inc. (CEI), reviewed but
determined where not feasible options for this site. Since that time there have
been no changes in the area associated with sanitary sewer availability, or
discharge to an infiltration gallery or spray field.
Alternative Option 1: Connection to regional Sewer System
Regional sanitary sewer collection services are not available to the ATI
facility at this time. Discharge to a regional sanitary sewer system is not
possible.
Alternative Option 2: Surface Discharge
The use of an infiltration gallery and use of injection wells were
investigated as potential discharge options. For the referenced site, ground
water contamination exists in fractured bedrock. The recovery wells are
constructed as bedrock wells. The use of an infiltration gallery is not a viable
option because the ground water would be pumped from the bedrock aquifer,
treated, and discharged to a shallow aquifer. A closed loop system is impossible
to demonstrate under these circumstances. Therefore, use of an infiltration
gallery is not a viable option. Low permeability shallow soils also make this
option less viable. Likewise, a closed loop system could not be demonstrated
using injection wells. The injection wells would have to be constructed in
Bedrock. Injection would occur through fractures in the bedrock and as such
complete capture is impossible to demonstrate. The presence of nearby
bedrock water supply wells makes this option not viable. — —
Alternative 3: Spray Irrigation
Spray irrigation is not a feasible discharge alternative. Most of the
contaminated area is capped by either asphalt or concrete pavement or is
covered by roads and buildings.
Alternative 4: Surface Discharge to an Open Ditch
Surface discharge to an unnamed intermittent tributary of Catawba
River, which eventually discharges to the Catawba River remains the only viable
option at this site.
